To (all whom, it may concern:

Be it known that I, \VILLIAM S. KISINGER, a citizen of the United States, residing at Bellev no, in the county of Campbell and State of Kentucky, have invented certain new and useful Improvements in I-Iorseshoe-Benders, of which the following is a specification, reference being had therein to the accompanying drawings.

The object of my invention is to provide a machine whose bending-jaws will be automatic ally closed by the advance movement of the bar or blank to which any desired shape is to be imparted, thereby dispensing with gearing, levers, cams, and other expensive and complieated appliances that have heretofore been employed for operating such jaws. This automatic action is eflected by pivoting the jaws to a bed-plate or other fixed member of the machine, and causing said jaws to remain nor mally in an open position, either by means of a spring or springs or other suitable appliances. The bar or blank is placed athwart the open end ot said pi voted jaws, in order that the advance of a die may drive the bar in between them, thus causing said jaws to close around the bar and thereby impart the desi red shape to the latter, as hereinafter more fully described; but the die, or the plunger that carries it, must be provided with a pair of lateral wings adapted to impinge against the sides of said jaws, so as to initiate their closure and thus relieve the blank of some of the strain incidental to the bending operation, as hereinafter more fully described.

In the annexed drawings, Figure 1 is a plan of my improved bendingmachine, the plunger being retracted, the jaws opened, and a blank or bar being inserted in front of the die. Fig. 2 is a transverse section of the machine, taken at the line 5 5 of the preceding illustration, the blank being omitted. Fig. 3 is asectionized elevation of a portion of the machine, a bent blank being shown in the act of being disengaged from the die. Fig. 4 is a plan of the under side of one of the bending or shaping jaws of the machine.

A A representportions of the side frame of a bending-machine, to which frame a stout bedplate, B, is securely bolted, said bed-plate being provided witha groove or raee,O, that coir fines to a proper path the reciprocating plunger or cross head D, the latter being driven by a pitman, E. This pitman may be operated either by a crank or eccentric,or otherwise, as the precise method of actuating the plunger is a matter of no consequence. Securely fastened to the upper surface of this plunger, and bearing against a shoulder of the same, is a detachable die, F, of any desired form, according to the blank that is to be bent; but in the present case said die is adapted for the manufacture of horseshoes,and is provided with a marginal flange, G, for the blank to rest upon. Furthermore, the plunger D or the die F is provided with two lateral wings, H H, between which a pit or recess, I, is located, the latter-being designed to admita toe-calk on the under side of the blank J.

K is an adjustable stop or gage that may be used for the end of the blank to bear against in case it is made without a toe-calk.

L Larestoutpivots l'or thebending or shaping jaws M M to turn around, the inner or opposing faces of said jaws being coueaved to correspond with the outer curve of the finished shoe, and being rabbetcd on their under sides at N N to admit the lateral wings H H. O is a springthat opens these jaws as wide as the stops P P will permit.

Adapted to rest upon the bed-plate B and in close proximity to the opposite sides of the die F are the forked ends or litters It R of a bellcrank, S, the latter being hung upon a suitable bearing, T.

U U are other forked ends at the opposite extremity of said bell-crank.

\Vhen my bemling-machine is in its normal position, as seen in Fig. 1, the plunger Dis retracted, and the shaping-jaws M M are opened by the stress of spring 0, thereby allowing the blank J to be inserted in front of the die F. The machine is now set in motion, and as the plunger D advances the extreme ends of the blank are slightly bent by contact with the 9 round corners of the jaws M M, thereby allow ing said blank to be forced in between the latter. As the plunger continues to advance, the

jaws are gradually but irresistibly closed around the blank, and by the time said plunger has completed its stroke said blank will be of a corresponding shape to the die. \Vhen the plunger retracts. carrying with it the bent blank, thejaws M M are gradually opened by the stress of spring (),and as soon as said plunger finishes its return stroke the pitman-coupling comes in contact with the forked ends U U of bell-crank S,and causes the latter to rock on its bearing T. This act raises the liftersR R, and thus disengages the bent' shoe J from the die F, as seen in Fig. 3, in which. illustration the normal position of said lifters R R is indicated by dotted lines.

From the above description it is evident a completelybent shoe is formed upon and'discharged from the machine every time the pl unger advances and retracts,and as the shapingjaws are operated automatically, they always act at the proper moment and can never close except when a blank is in a suitable position to be compressed around the die.

It is also evident that by disposing the lateral wings H H in such a manner as to compel them to impinge against the sides or vertical walls of the rabbets N N of jaws M M. said wings H H initiate the closure of said jaws before the blank has advanced beyond a certain predetermined point; consequently a portion of the strain incidental to the closure of said jaws will be sustained by these Wings.

The device that disengages the bent shoe from the die may be modified by providing the pitman-coupling with a stud,V, upon which to hang a bellcrank, W W, as indicated by the dotted lines in Fig. 3. ThelongarmW of this device serves as the lifter, and is thrown upwardly by the contact of the short arm W with a fixed bar or other stop, X, it being understood that this arrangement of bell-crank is duplicated on the opposite side of the pitmancoupling. which the crank or other drivingdevice is applied may be considerably elevated, so as to incline the bed-plate B at such an angle as to cause the bent blank or shoe J to drop off as soon as it is disengaged from the die.

I claim as my invention- The combination,-in a bending-machine, of the bed-plate B. provided with a pair of pivoted and rabbeted shapingjaws L M N L M N, and reciprocating plunger D, which latter carries a suitable die, F, and is furnished with a pair of lateral wings H H that initiate the closure of said jaws in the manner herein de scribed.

In testimony whereof I affix my signature in presence of two witnesses.
